To all whom, itmay concern:

Be it known that we, THOMAS C. MOSELY and ALPHEUS H. KINGMAN, citizens of the United States, residing at Chicago, in the countyof Cook and State of Illinois, have invented a new and useful Improvement in Gasoline-Heaters, of which the following is a specification.

Our invention relates to the class of heaters employing refined fluid hydro-carbon, or gasoline as the fuel and in which the burner is adapted to vaporize, by heat, the gasoline a view in broken elevation of ourimproved heater applied to awater receptacle shownin section and as partly broken. Fig. 2 is a broken sectional view of the alcohol-supply holder and valve for controlling and proportioning the feed therefrom. Figs. 3 and 4 are perspective views of details. Fig. 5 is a plan view of the flame spreading plate.

A is a gasoline-burner comprising the hollow circular and peripherally bulging head 7', having slits forming openings q extending at close intervals around the periphery transversely through the same, the head being flat and closed at its upper and lower sides. The burner-head r is secured upon a disk p having a diagonal duct 0 on its under side with one end of which the supply-pipe n communicates, while the opposite end leads into a short tube m terminating in a cross-tubel provided at one extremity with the burnernipple k and having inserted into its opposite end a supply-regulating valve 71. The nipple k coincides with the short tube 10' leading into the burner-head at its base.

The parts of the burner as thus far described are old and well-known, being shown to serve for illustrating our improvements hereinafter described, but which are not lim ited to use in such particular connection.

The bu rner-head r is surmounted by a flamespreading plate h, preferablya disk of sheetmetal, and which should be provided with h is fastened flatwise over the upper side of.

the burner-head r in a manner, as indicated, to leave a narrow space s between the two, which, as practice has demonstrated, greatly facilitates the burning.

B is an annular diaphragm, the diameter of the opening gin which is less than that of the plate It, whereby the latter overlaps the edges of the diaphragm-opening above which it is supported, as shown and hereinafter more fully explained.

C isaform of water-heater especially adapted for use with our improved burner, by having an inverted dish-shaped base ffrom which a ventilating pipef' extends centrally through the water-holder, which is supported around the edge of its base in a ring recessed circumferentially on its upper side to receive it and the interior of which is partially filled by the annular diaphragm B supported on the,

ring.

At the lower end of the nipplek is an extension forming a post 00, to which is rigidly fastened in horizontal position a flanged plate affording a rest 6 for a dish D having arecess co in its rear end to adapt it there to embrace the post a: when the dish is supported in operative position on the rest. We form the dish D of metal and pack it internally with asbestus fiber or mineral wool, in, to absorb the alcohol used initially in starting the prevent spilling or sloppin g of the alcohol and also, the packing being a noirconductor of heat, to avoid such heating of the dish as would prevent it from being always in condition to be removed by hand for refilling, which may be done by merely slipping it off its rest 6, upon which it is as readily replaceable.

With the alcohol-supplying attachment E, however, the dish D need rarely be removed. The attachment E comprises a receptacle 61 adapted to hold, say, about a pint of alcohol (or other suitable spirit) and having a tubu lar opening d in its base, leading into a horizontal tube 0 closed at one end near which a supply-pipe 0' leads to the dish D. In the burner, as hereinafter described, thereby to tube 0 is a piston b containing a chamber 12' extending transversely through it and adapted to hold a few spoonfuls of alcohol, and which coincides with the outlet d when the piston is drawn outward, as it normally is, so that the chamber b is normally in position to fin.

Alcohol is desirable, as a medium for starting the burner to vaporize initially the gasoline by reason of its being non-odorous, which the gasoline is not, and if used for the purpose, is more or less offensive on account of the odor and the smoke it generates.

To start the burner, enough alcohol is supplied to the dish D, either upon removing it for the purpose in the manner described, or by forcing inward the piston 17 till its chamber 19, which thus apportions the supply, coincides with the pipe 0, into which the contents empty and thence enter the dish, the piston, meantime, preventing escape of any of the contents of the holder cl and being returned to its normal position when the chamber- 19' has been emptied. The alcohol in the dish is then ignited and heats the pipe Z into which the gasoline supply is admitted, thereby generating the required vapor from the gasoline before it emerges from the nipple is whence it passes into and through the burnerhead 7", where it is lighted, under the plate It. The air passing through the opening in the diaphragm B mixes with the flame, and the draft spreads the latter over the entire area of the base of the receptacle 0, at the same time producing perfect combustion of the liquid fuel and an intense heat, and combustion is materially assisted by the free circulation of air across the space 8 between the top of the burner-head and base of the plate h.

What we claim as new and desire to secure by Letters Patent is In combination, a receptacle 0 having an inverted-dish-shaped bottom supported on a ring f and containing an annular diaphragm B, and a burner A, having its burner-head supported over the opening in the diaphragm and surmounted bya spreading-plate h greater in diameter than the diaphragm-opening and afiording a space 3 between it and the burnerhead, substantially as described.
